The main activities of the economically active population around
The Iztaccihuatl and Popocatepetl volcanoes region lie in the
primary sector (65- 90%). Of the people working in this sector,
those dependent on agricultural or pastoral activities generally
have an income significantly lower than the minimum wage in Mexico.
Of the activities in the area, these agricultural, pastoral, and
forestry activities probably have the most direct effect on the
ecology of the volcanoes and its immediate surroundings.
Traditional farmers, producing crops such as beans, pumpkins and
cucumbers, generally work on small fields using traditional methods
and animal traction. Modern farming, geared towards intensive
production develops on larger sites making use of modern machinery,
fertilizers, and pesticides. As the area under agriculture
continues to increase every year, the attendant opening of large
forested areas, soil modification, and ensuing erosion make it
almost impossible for forest recovery. Extensive forestry in the
region mainly concerns cutting and collecting wood, cutting
Pinus-branches for torches or for utensils for open-fire cooking,
collection of mushrooms, and hunting. Although these (often
clandestine) activities seem to be small-scale, their adverse
effects on the forest have been substantial. Weekend visitors from
Mexico City heavily dominate recreation, with tourism concentrated
near the roads leading to and inside the park. Lacking organization
and facilities, most recreational activities have had significant
environmental impact on the area In many countries, the decline of
nature has occurred because of changes in land use.
